Abstract
Dairy products are one of the indispensable foods in people's life. However, reports about the quality and safety of dairy products often appear. In this paper, a dairy product quality and safety traceability system based on consortium blockchain is proposed by using block chain technology. In addition, the traceability link in the dairy supply chain is defined, and the basic framework and traceability bar code of the traceability system are designed. The system guarantees the integrity and security of the traceability information from the technical level, and provides the dairy traceability service for the government, enterprises and consumers.
Highlights
Dairy products, as a special category of agricultural products, have a long industrial chain and involve many subjects
Research in developed countries on the traceability system of dairy products is relatively early than developing country
Domestic government departments have done a lot of work in dairy quality supervision through improving laws and regulations, but the scope of application of traceability system is very limited, and there is no unified standard for the content of traceability code
Summary
As a special category of agricultural products, have a long industrial chain and involve many subjects. It is formed by the cooperation of the farming industry, processing industry, logistics industry, sales industry and other market entities, involving multiple interests. Research in developed countries on the traceability system of dairy products is relatively early than developing country. The problems lead to the asymmetry of traceability information, and it is a huge challenge in completing the traceability of the whole industrial chain. Blockchain is a distributed database, which can avoid illegal deletion, falsification and tampering of data and realize information sharing. It can trace the whole chain of dairy products and solve data security problems
